Unit Summary
In this unit pupils will accurately and efficiently solve multi-step addition and subtraction problems. They will understand and explain how both addition and subtraction equations can be used to describe the same additive relationship.
Lesson Summary
You will learn to solve problems using scaled bar charts, pictograms and tables.
Key Notes
- A key on a pictogram and the scale of a bar chart can provide key information about the data shown.
- Annotating pictograms and bar charts helps to solve problems.
- Rearrange equations to make it easier to calculate missing numbers.
Vocabulary To Learn
- Bar chart: A bar chart uses rectangular bars to show different values.
- Pictogram: A pictogram uses pictures to show information.
- Table: A table has information arranged in rows and columns.
Common Mistakes To Avoid
- Pupils may find it tricky using scales to read bar charts, especially when the scale uses multiples of five.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A key on a pictogram and the scale of a bar chart can provide key information about the data shown. Annotating pictograms and bar charts helps to solve problems.
2. Use this key word in a maths sentence and explain it clearly. 'Bar chart'
A bar chart uses rectangular bars to show different values. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may find it tricky using scales to read bar charts, especially when the scale uses multiples of five. Correction: Encourage pupils to think about where intermediate numbers are on bar charts (e.g. numbers from 10 to 15). They may count from one number to another or make marks to show approximately where numbers would be found.
